Platynereis pulchella   Gravier,  1901 (Marine Worm)
Organism information awaits expert curation
Class: Polychaeta

Size: 15-30 mm, Heteronereis stage, about 15 mm., male with two regions.

In the atocous condition this species is so close to Pl. dumerilii with a single row of paragnaths in the groups VI instead of two, and by slightly different falcigers. In all but a few anterior segments, there are one or four dorsal homogomph falcigers, the terminal piece with downward curved, smooth tip and conspicuous terminal ligament having its basal attachment as far down as the tip of the articular cup.
But the epitocous condition is quite different from Pl. dumerilii and close to that of Pl. polyscalma, differing only in the presence of the said dorsal homogomph falcigers in the last segments of the anterior part and in the blades of the swimming bristles whose fringes are very fine and difficult to see, and, last, the terminal, simple, ribbed bristles are finer.
